TL,DR: My Recommended Druid Healing Strategy
Talents: NS, SotF, HotW (normal)/NV (Heroic)
Glyphs: Glyph of Blooming, Glyph of Regrowth, (Glyph of Healing Touch – if you lack 4-piece t14)
Between breaths: Get 3xLB up, refresh it with 4 sec to Sun Breath cast; keep Rejuvenation rolling (but do not overwrite a Bathed-in-Light-boosted Rejuv); use Swiftmend as soon as it comes off cooldown, then hold it ’til the next Sun Breath; cast Healing Touch unless you have Omen of Clarity/Clearcasting, in which case cast Regrowth.
During breaths: Swiftmend, Rejuvenation, Regrowth, Regrowth, Wild Growth or NS/HT; allow LB to bloom
